THE MIRACLE OF THE IMMUNE SYSTEM - Harun Yahya

THE MIRACLE OF THE
IMMUNE SYSTEM

ORGANS EMPLOYED
IN DEFENCE

Warrior Production Centre: The Bone Marrow

Bone marrow

When atom bombs were dropped on Hiroshima and Nagasaki, many people exposed
to the radiation released by the explosions died 10 or 15 days later from
internal bleeding or infection. Animal experiments conducted to explore
what happened to such casualties revealed that whole-body radiation kills
the generative cells in blood-forming and lymphoid organs. Without the
cells responsible for clotting and for fighting invaders, the body dies.6

The factory of these vital cells is the bone marrow. The interesting
point is that many diverse products are produced in this factory. Some
of the cells produced here play a role in the production of phagocytes,
some in the coagulation of blood, some in the decomposition of substances.
These cells differ in function just as they differ in their structure.

It is remarkable that a very special production system has been established
for many different cells that work towards the same goal.

Here, there seems to be an impregnable barrier for the theory of evolution.
This is because the theory of evolution claims that multi-celled organisms
have evolved from one-celled organisms.

So, how can coincidentally formed cells build a system capable of producing
new cells in the very structure they have constituted? This is similar
to thousands of bricks, which have burst into the air as a result of an
explosion at a brick factory, having fallen down on top of each other
by chance and, in the process, making a brand new building. Moreover,
in this building there must also be another factory to build new bricks.

It has to be remembered that the creation of a human body is a million
times superior to that of a building. The cell, which is the building
block of the body, has a design too perfect to be compared with any man-made
product. This analogy between the cell and the brick has simply been made
in order to clarify how deceitful the hypothesis of evolutionists is.

The Faculty In Us: The Thymus

Organs functioning in the body's immune system

On biological examination, the thymus would seem to be an ordinary organ
without any particular function. The work it does, however, when studied
in detail, is quite unbelievable.

In the thymus, the lymphocytes get some sort of training. No, you have
not misread this. The cells receive training in the thymus.

Training is an information transfer, which can be exercised on beings
with a certain level of intelligence. So there is an important point that
needs mention here. What gives the training is a lump of meat, which is
the thymus, and what receives it is a miniscule cell. In the last analysis,
both are unconscious beings.

Immune cells (T lymphocytes) trained in the
thymus.

At the end of this training, lymphocytes are equipped with a very important
body of information. They learn to identify the particular characteristics
of the cells in the body. In some sense, the lymphocytes are taught the
identities of the body cells. Finally, these cells leave the thymus loaded
with information.

Thus, as the lymphocytes function in the body, they do not attack the
cells, the identity of which they have been taught. Any other cell or
foreign matter is attacked and destroyed by them.

For years, the thymus was considered to be a vestigial organ by evolutionist
scientists and used as so-called evidence for evolution. In recent years,
however, it has been revealed that this organ constitutes the wellspring
of our defence system. After this was understood, evolutionists, who once
proclaimed the thymus to be a vestigial organ, now advanced a totally
opposite theory for the same organ. They claimed that the thymus did not
exist before, and originated through gradual evolution. They still maintain
that the thymus formed in a longer evolutionary period than many organs.
However, without the thymus, or without its being fully developed, T cells
could not have learned to identify the enemy and the defence system would
not have functioned. Someone without such a system would not survive.
Even your reading this sentence now is proof that the thymus was not created
through a long evolutionary process, but has always existed, perfect and
intact in all respects, since the advent of the first human being.

A Versatile Organ: The Spleen

Another wondrous element of our defence system is the spleen. The spleen
is made up of two parts: red pulp and white pulp. The fresh lymphocytes
produced in the white pulp are first transferred to the red pulp and then
join in the blood stream. A detailed study of the operations carried out
in this organ, which is dark red in colour and located high up the abdomen
reveals an extraordinary picture. Its quite difficult and complicated
functions are what make it so wonderful and extraordinary.

The duties of the spleen, such as contributing to cell production, phagocytosis,
conservation of red blood cells, and immunity construction, are at least
as important as they are difficult. Certainly, the spleen is a lump of
meat just like all our other organs. Yet it displays a performance and
a degree of intelligence unexpected from a lump of meat. It organises
everything, not allowing any problems to occur, and works without rest.
Indeed, the spleen works strenuously for the human from the moment of
his birth, and continues its function as long as Allah wills.

He is Allah - the Creator,
the Maker, the Giver of Form. To Him belong the Most Beautiful Names.
Everything in the heavens and on the earth glorifies Him. He is
the Almighty, the All-Wise. (Surat al-Hashr: 24)

Cell Production

The bone marrow of the baby in the mother's womb is not entirely able
to fulfill its function of producing blood cells. The bone marrow can
perform this function only after birth. Would the baby be anaemic in the
meantime?

No. At this stage, the spleen comes into play and takes control. Sensing
that the body needs red blood cells, thrombocytes, and granulocytes, the
spleen starts to produce these cells in addition to lymphocytes, which
is its main duty.

The spleen, however, is an unconscious lump of meat. It is not capable
of assuming such a responsibility. Besides, even if it did, how would
it be equipped with the required information and components to produce
the extremely complex cells and proteins? Allah, Who created the human
body, created the spleen in such a way as to enable it to take on other
responsibilities in addition its own task when necessary, and equipped
it with the necessary stimulus and production systems.

Phagocytosis

The spleen contains a large number of macrophages (cleaner cells). These
engulf and digest old and damaged red blood cells, some damaged blood
cells and some substances that are carried to the spleen through the blood.

There is a very important chemical recycling system at work here.

The macrophage cells in the spleen convert the haemoglobin protein, which
is found in the composition of the red blood cells they have engulfed,
to bilirubin, a bile pigment. Then, the bilirubin is released to the venous
circulation and sent to the liver. In this form, it can be discharged
out of the body along with the bile. However, the iron molecule found
in the bilirubin which is about to be discharged out of the intestines
along with the bile, is a rare material which is very valuable for the
body. For this reason, iron is absorbed back in a certain region of the
small intestines and from there, it first goes to the liver and then to
the bone marrow. Here, the purpose is both to discharge the bilirubin,
which is a harmful substance, and, at the same time, to regain the iron.

The bilirubin balance is crucial for our body. This is because even the
slightest problem in this system would lead to serious outcomes. One of
the best examples is that when bilirubin goes above a certain level, jaundice
develops in the body. However, the cells in our body, as if they are aware
of this danger, discharge the harmful materials from our body with a great
precision while they select the useful ones among them and put them into
use once again.

Red Blood Cell Storage

The skills of the spleen do not end here. The spleen stores a certain
amount of blood cells (red blood cell and thrombocytes). The word "store"
may conjure up an image of a separate compartment in the spleen that can
be used for storage. The spleen, however, is a small organ, and it has
no space to use as a storage room. In such cases, the spleen expands to
make room for red blood cells and thrombocytes. A spleen enlarged due
to some diseases may also have an enlarged storage space.

Contribution To War

When a microbial infection or any other malady develops in the body,
the body mounts a defensive attack on this enemy, prodding the warrior
cells to multiply. At such moments, the spleen enhances lymphocyte and
macrophage production. Thus, the spleen also participates in the "emergency
operation" that is launched at times when disease could harm the human
body.

Another Production Centre:
The Lymph Nodes

In the human body, there is a police force and a police intelligence
organization scattered throughout the body. In this system, there are
also police stations which have policemen on guard, and which produce
new policemen when required.

This system is the lymphatic system and the police stations are the lymph
nodes. The policemen of the system are lymphocytes.

The lymphatic system as it stands is a miracle performed for the benefit
of mankind. This system comprises of lymphatic vessels that are diffused
throughout the body, lymph nodes that are located at certain spots on
these vessels, the lymphocytes produced by lymph nodes, which patrol in
the lymphatic vessels, and the lymph fluid circulating in the lymphatic
vessels in which lymphocytes swim.

The system works as follows: The lymph fluid in the lymphatic vessels
spread throughout the body makes contact with the tissues located around
the capillary lymphatic vessels. The lymph fluid that returns to the lymphatic
vessels right after this contact brings along some information about these
tissues. These pieces of information are transmitted to the nearest lymph
node located on the lymphatic vessels. If any hostile action has started
in the tissues, its knowledge is forwarded to the lymph node through the
lymph fluid.

In case any danger is sensed following the examination of the nature
of the enemy, an alarm is given. At this point, the rapid production of
lymphocytes and some other warrior cells starts in the lymph nodes.

After the production stage, the new soldiers are transported to the front
where the battle is fought. These new soldiers will travel from the lymph
nodes to the lymphatic vessels through the lymph fluid. The soldiers,
which are diffused into the blood stream from the lymphatic vessels, finally
reach the battleground. This is why the lymph nodes in the infected region
swell first. This shows that the lymphocyte production has increased in
that region.

Now, let us summarise the system:

- A special transportation system that covers the length
and breadth of body.

- Lymph node stations dispersed throughout different
regions of the body.

- The intelligence operation directed at the enemy cells.

- Production of soldiers according to the results of
the intelligence report.

It is impossible for this system, which would collapse in the absence
of even one of its elements, to have originated by developing gradually
over time. For instance, a system with lymph nodes and lymphocytes, but
without lymphatic vessels, would not be of any use. The system can work
properly only if all its elements are created simultaneously.
